Subversion error sqlite attempt to write a readonly database

Because of the extensive testing and widespread use of SQLite, bugs that result in database corruption tend to be very obscure.

[android-developers] Problems reading/writing to SQLite db on SD card.

Try writing to the repository: In other words, opening and using a database file that has two or more names results in behavior that is undefined and probably undesirable. When required to attempt to detect a hot-journal file, if the call to xAccess required by H indicates that a journal file does not exist, then SQLite shall conclude that there is no hot-journal file in the file system and therefore that no hot journal rollback is required.

However, new result codes, and especially new extended result codes, might appear in future releases of SQLite.

If it is, then it is a hot-journal file and SQLite tries to roll it back see section rollback Master journal file pointers? If the database schema was changed by some other process in between the time that the statement was prepared and the time the statement was run, this error can result.

Database pages leak from the free page list When content is deleted from an SQLite database, pages that are no longer used are added to a free list and are reused to hold content added by subsequent inserts.

There is a race condition that can occur when two separate database connections both try to start a transaction at the same time in WAL mode. If, while opening a read-only transaction, SQLite encounters an error while attempting to detect or roll back a hot journal file, then the shared-lock on the database file is released, no transaction is opened and an error returned to the user.

If the database file header is successfully read from a newly opened database file, the connections expected page-size shall be set to the value stored in the page-size field of the database header.

Multiple links to the same file If a single database file has multiple links either hard or soft links then that is just another way of saying that the file has multiple names. The likelihood of an application encountering an SQLite bug is small.

A similar problem occurs if a database file is renamed while it is opened and a new file is created with the old name.

Modifying the contents of a database page. If the call to xCheckReservedLock required by H fails due to an IO or other internal VFS errorthen SQLite shall abandon the attempt to open a read-only transaction, relinquish the shared lock held on the database file and return an error to the user.
